COPY-HOLDERn SPECIFICATION forming part of Letters Patent No. 431,934, dated July 8, 18290.

Application filed May 15, 1890. Serial Noi 351,886x (No model.)

To all whom it may concern:

Be it known that I, CHARLES E. BRUN- THAvER, a citizen of the United States, residing at Vashington, in the District of Columbia, have invented certain new and useful Improvements in Copy-Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of indicators which are adapted to show by successive steps a series of objects-such as the names of stations on a railroad or of streetcrossings on a street-car line-or to show aseries of parts occurring in the same objectsuch as lines of proof-sheet to be read or of writing to be copied, or such as the names of periods of time on a calendar, the.; and the object of this invention is to simplify and to render more reliable and accurate the operation of :my earlier invention, on which an application, Serial No. 344,622, was iiled in the Patent Office March 20, 1890, to adapt it peculiarly as a' copy-holder for use with typewriting machines, dto.

To this end my invention consists in the construction and combination of parts forming a copy-holder hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure I is a front elevation or" my copyholder. Fig. Il is an end View of the saine with certain parts broken away to show parts beyond; and Fig. III represents a vertical section at oo, Fig. l.

5 represents the bed-piece, adapted to rest upon any table.

6 6 are the two end portions of the frame, secured by screws to the bed-piece and connected together by a cross-bar 7, having a wooden portion 8 secured to it.

9 10 represent cylindrical rollers journaled in the ends 6. The lower roller 10 is in permanent bearings, but the upper roller 9 is free to rise and fall in its bearingsJ and is pressed down by a spring lland follower 12 at each end to insure its pressure upon the paper 13, which is the copy to be passed between the rollers. The rollerlO is provided with aknob 14, by means of which it may be rolled rapidly forward to draw the copy or other paperinto place, and with a gear-wheel 15, engaging an intermediate gear-Wheel 16, that is journaled to revolve freely upon a stud 17 ,which is iiXed to the frame 6.

18 is a ratchet-wheel journaled upon the same stud 17 and rigidly fixed to the intermediate Wheel 16.

19 is a lever provided with a finger-knob 2O and journaled upon the same stud 17, and further provided with a series of pawls 21, whose free ends are forced into engagement with the ratchet-wheellS by means of springs 22, one spring for each pan' l.

23 is a slotted segment secured to the frame 6 and having anoffset to carry its are beyond the gear-wheel and lever.

24 is a stop-p n in the path of the lever 19, and made adjustable along the said segment 23 by means of a setserew 25, passing through a screw-nut fitted to slide but not to turn in the slot in the segment.

26 is a spring coiled around and secured at its inner end to a hub of the lever 19 and secured at its outer end to along screw 27, which stands as a fixed stud from the frame 6. The spring 26 pulls the lever 19 and pawls 21 backward until a shoulder of the lever rests normally against a shoulder 2S of the fixed segment 23.

29 is a drum neatly concealing the coil of the spring 26, but open at one side to permit the'arm of the spring to reach its point of attachment 27.

39 is a sash provided with hinges 30, which attach it to the cross-bar 8 of the frame.

31 is a shield fitted to slide vertically in grooves 32 in the end bars of the sash.

33 is a plate or table secured by screws 34 to the ends of the frame and located tangent to the lower roller 10 and justbelow it to serve as a backing or table to support the paper should it be found necessary to write upon it while it is in the machine.

The operation is as follows: To insert the paper, iirst raise the sash 39 and swing it -up out of the way. Then put the upper edge of the paper between the rollers 9 10 and by turning the knob 14 draw the paper in a little. Then turn its lower end back under the plate 33, as shown in Fig. III. Now bring the sash IOO down to place in front of the paper. Then bring a line of the paper exactly to the upper edge ot' t-he shield 31. Press the lever 20 down until the next line on the paper is exactly at the edge of the shield, and then by means of the thumb-screw 25 tix the stop-pin 24 against the lever. If this adjustment is accurately made, every pressure upon the lever will bring up another line of the copy. It will be 0bserved that there are three pawls 2l of different Alengths to engage a tooth one after another, so that whatever may be the space between lines some one of the pawls is ready to engage a tooth without loss of space. By properly proportioning the gearing described this machine may be gaged to draw the copy along any space varying from one thirty-second of an inch to several inches at a step, so that it maybe adapted for reading printed proof in fine type or for reading copy in the widest-spaced writing. It is here shown with a bed-piece adapted to stand upon a table; but it l would require only common mechanical skill to provide a clamp-screw whereby this copyholder may be attached conveniently to the frame of a type-writing machine. lts means of adjustment render it applicable to a great many uses not here enumerated.

Having thus fully described my invention,

what I believe to be new, and desire to secure by Letters Patent, is the following:

l. The combination, in copy-holders, of a frame, two cylinders journaled therein one above the other and one of them provided with a gear-Wheel, an intermediate wheel j ournaled upon a stud fixed on the frame and gearing with the aforesaid Wheel and having a ratchetwheel fixed to it, a lever journaled upon the said stud and provided with a series of pawls and springs to engage the aforesaid ratchetwheel, a spring for returning the lever, a lixed stop at one end of the path of the lever, and a stop adjustably ixed in its path, substantially as shown and described.

2. The combination, in copy-holders, of two feed-rollers journaled in a frame and one of them provided with a gear-wheel, an operating-lever journaled upon a stud fixed on the frame and provided with pawls, a ratchetwheel engaged by the said pawl and fixed to an intermediate wheel journaled upon the said stud and gearing with the said wheel upon the roller, a slotted segment iixed tothe frame and having a shoulder ending the path of the said lever, and a stop-pin provided with a screw-nut adjustable along the slot in the said segment in the path of thelever, substantially as shown and described.

3, The combination, in copy-holders, of two feed-rollers jonrnaled in a frame, a sash having a shield in it hung in front of the rollers, and an aperture through the sash above the shield, and a plate fixed nearly tangent to the lower roller between the same and the said shield, substantially as shown and described.

4. The combination, in copy-holders,of two feed-rollers journaled in a frame and a sash hung in front of the rollers upon hinges and having an aperture exposing to view the region of the rollers, substantially as shown and described, whereby the rollers may be uncovered to place the paper between and below them and then the paper be partially concealed.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES E. BRUNTHAVER.
